Energy From The Sun : Solar Energy Essay

Climate change has been a major global issue for the past years and the use of non-renewable energy sources is only adding to the pollution that is responsible for the destruction of our planet. One of the biggest indicators of unproductivity is the lack of utilization of renewable energy sources. Currently, only a small percentage of Florida’s energy is attained by renewable sources (U.S. Energy Information Administration, 2017). The state of Florida is capable of at least partly running on solar or hydro power, but most schools don’t take advantage of the resources that are naturally occurring. Specifically, the School District of Palm Beach County operates a total of 112 schools, as reported by the school district website. Of them, ten have achieved LEED certification, a rating system that certifies “green schools,” meaning that they are energy efficient and use sustainable resources. This leaves the other 102 schools to continue to use up non-renewable resources and contribute to the mass pollution of the Earth. According to XCel Energy, schools spend billions of dollars yearly, just to deal with the daily expenses. However, a significant portion of a school budget is used for utilities such as air conditioning, water, and electricity. Both individual schools and the school district could save money by taking advantage of the natural resources in Palm Beach County. If schools were to incorporate more renewable

     Solar energy is the most ancient kind of energy found on earth, for it is as old as the sun. "Solar" means from the sun. The earth is only one of the many planets which is bathed in the sun's overflowing energy. Every second the world receives 95.8 trillion watts of power…just think about that for a minute. Think about how much power the earth just received in the time it took you to read this sentence? It is well beyond the amount of power used in one day. It has the potential to satisfy all our energy needs forever without ever having to use the pollutive fossil fuels ever again. "The problem however, does not lie in the limited source, as do fossil fuels, but in harnessing

In this modern fast paced world that we live in, there are many issues that are looked over, energy is one of these. As a world, we are dependant on dwindling fossil fuel supplies and take for granted electricity, oil, and gas. There are four completely renewable sources of energy around us that should be used and developed, they are: wind, growing plants, flowing water, and the sun. These sources of energy are the ones we should be tapping, because they are reliable and renewable. Harnessing the suns energy is the most certain and ultimate energy source. Looking at a brief history and some facts about solar energy, a glimpse of the future can be seen, a future not dependant on

Most of the processes that are critical for our day-to-day lives are driven by energy provided by the Sun. Energy from the Sun warms the planet and keeps the global temperature within a range that allows life to flourish. The energy stored in the food you eat can be traced back to the Sun, through the conversion of solar energy to chemical energy in the process of photosynthesis. You might think that the gasoline that makes your car run or the oil that

Photosynthesis Introduction: Photosynthesis is a process by which light energy is converted into chemical energy. Understanding energy conversions is not trivial, and this bio-coach activity is designed to enhance our understanding and retention of the content by illustrating and animating the fundamental processes involved in photosynthesis. An Overview of Photosynthesis: Photosynthesis converts light energy into the chemical energy of sugars and other organic compounds. This process consists of a series of chemical reactions that require carbon dioxide (CO2) and water (H2O) and store chemical energy in the form of sugar.

Imagine a world without light, a world filled with so much darkness that it would be nearly impossible to see anything, to use anything or to even function. A world without light would be a world without energy, without being able to use our phones 24/7, a world without all the comforts, mainly a world with hardships and struggles. We live in a world where energy is needed for everything. Nothing really works without electricity. For example, Energy is constantly being used to charge cellular devices, warm food in the microwave or even to charge electrical cars. The world is shifting it went from the extracting of unnatural fossil fuels to the discovery of a more natural way call solar energy. In order to know how crucial solar energy is it

I am certain that all have heard of the terms green house gases, fossil fuels, and global warming. Have you ever questioned what will happen if nothing is done about the environmental problems facing the world today? What if I answer you that, we can merely use the power from the sun to power up our entire planet without the use of harmful energy sources, which affect our atmosphere? The power from the sun is what we call solar power. Solar power is the energy that comes from the sun as light and heat energy, and then it is later converted into electrical energy through solar panels (Nelson, 2008). This kind of power is completely free, right? Why should we put a lot of expense on other sources of energy, when there is a complete free

Solar energy is an eco-friendly alternative to fossil fuels. Our planet has been experiencing an average increase in global temperatures. Slowly but surely our planet is deteriorating, unless we change our form of energy into a greener alternative. Deterioration of our planet may occur at a faster rate. The depletion of fossil fuels is detrimental to our environment. By substituting fossil fuels with the solar energy, our planet will benefit. These benefits include: reduced climate change, beneficial economic opportunities on both a large scale benefitting our government and on a smaller scale helping individuals decrease their energy bills, and solar energy is renewable and sustainable.

Solar radiation, planetary energy and geothermal energy are the three forms of renewable energy available on earth. Radiation from the sun is the highest source of energy and the obtainability of these sources alters. In a nuclear fusion process in the sun, hydrogen is transformed into helium. It is in the form of electromagnetic waves that the surface of the sun radiates this energy. This will

In order to understand this, we have to understand that the Sun and Earth are both sphere’s that are constantly moving. According to Kitchen, the sun can emit 174 petawatts of energy into space and it is emitted everywhere, not just Earth (2014). Because Earth is a sphere and rotates on a tilted axis, it only absorbs small amounts of radiation.

Comparing solar energy’s benefit as an infinite clean energy source and the problems of environment and pollution

The use of sunlight is to supply the needs of humans like energy is a primary source to survival on earth. The sun’s energy is able to feed animal need’s. Only green plants are able to convert the energy from the sun into fuel and food. Most of our food and fuel are made through the sun with a process of photosynthesis.

Solar energy is a photovoltaic effect. It is the act of electricity generated from sunlight. Sunlight begins with the sun. The sun is made up of four layers which are: the core, the radiative zone, the convective zone, and the photosphere. These layers have their own purposes that creates light. Light is a form of radiation, electromagnetic radiation, which is made up of photons. The core produces the energy by hydrogen atoms(H). Then it converts to nuclei of helium. The temperature of the sun is 5,778 Kelvin (9940.73 Fahrenheit) because of how much pressure it has. The pressure creates Nuclear Fusion which is what creates heat and light.

Solar energy and its use isn’t new to the world. It has been used by various societies beginning from 7thCentury B.C, when the sun’s heat was concentrated by glass and mirrors to light fires. Today, we have everything from solar-powered buildings to solar-powered vehicles. By and large solar technology has some environmental, economic, psychological and ethical implications for our society. Actions taken by companies and individuals to increase the use of solar technology will create good local jobs, improve our environment and reduce our dependence on foreign oil while doing what’s ethical and moral for our society.

Abstract: The current energy situation with fossil fuels as the main source of the world’s energy has two main flaws: fossil fuels contribute to global warming via the greenhouse effect and they are limited in the quantity that remains. Solar power solves both of these problems and can be captured by utilizing photovoltaic cells. However, photovoltaic cells have their own drawbacks due to their high costs of installation and maintenance.
